You need to have a friend sit inside the car as you watch the windows go up with the top up. If the front or the back rises faster than the other end, you have a regulator going out. If the front and rear parts of the glass go up at the same time, you may need to simply do a reset on the windows, which has been discussed on the forum but I can't remember where! Do a search.

There is a microswitch in each door handle to drop the window a quarter of an inch and while many think these switches are going out, it's often the regulator. Because our cars are convertibles, we raise and lower the windows a lot more than say, a 996 or Cayman.

My windows do seem to clip the top when I shut the door fast, but it's not bad enough for me to worry about.
